Moisture sorption characteristics of lal peda at different storage temperatures

► Moisture sorption isotherms of lal peda were analyzed at 10, 25 and 37 °C. ► MSIs obtained were of sigmoid shape (type II) at all temperatures. ► GAB model was fitted best to the sorption data of lal peda at three temperatures. ► The Mo values were 0.285%, 0.355 % and 0.423 % at 10, 25 and 37 °C, respectively. ► Heat of sorption increased with decrease in moisture content.
